Moody's Utah 58 Apache

The cab needs to be level with the frame. Put a level on the frame and get it leveled or get a reading on the angle it is sitting at. Then level the cab to the frame with shims or whatever. Front to back and side to side.Then check/replace the rad support bushings and level up a fender to the door. Assuming the door fits the cab as it is supposed to be fitted to the cab opening before worrying about fenders. Do one side then the other.
Did you ever do a frame check for straight, square and sag? Sometimes these old tricks have a history you dont know about.
